Ordinarily two treatments, one about three weeks after the petals are off and the other four or five weeks later, are sufficient. A weak Bordeaux mixture, such as 3 pounds of copper sulphate and 3 pounds of lime to 50 gallons of water, is effective in controlling this disease, Bordeaux mixture of full strength not being required. b a For a combination treatment...
Page 43 - Sporotrichum thebaicum Ehrenb. Sporotrichum sporulosum Sacc. Fusarium sp. undet. Contrary to the general belief that soil fungi are largely confined to acid soils, the writers have found that the cellulose-dissolving forms multiply with great rapidity in alkaline soils when cellulose in the form of filter paper was added. While only preliminary studies of cellulose destruction in our soils have been made, the great variety and vigor of the cellulosedissolving fungi lead to the conclusion that cellulose...
